X Toolkit Intrinsics
 libXt, the X Toolkit Intrinsics, is an abstract widget library upon which
 graphical widget libraries for the X Window System (such as Athena and
 LessTif) may be developed; the Intrinsics provide a number of useful
 interfaces to X conventions and protocols, in many cases reducing a long
 series of Xlib calls to just a couple of Xt calls.
